Lack of direct evidence for a functional role of voltage-operated calcium channels in juxtaglomerular cells [PDF]

, 1990
In this study we have examined the role of voltage-gated calcium channels in the regulation of calcium in juxtaglomerular cells. Using a combination of patch-clamp and single-cell calcium measurement we obtained evidence neither for voltage-operated ...

Heterogeneous Phosphotungstate Catalyst Mediated Efficient Alcoholysis of Furfuryl Alcohol into Long-Chain Levulinates

BioResources, 2023
The synthesis of alternative fuels from biomass has emerged to be a vital strategy to maintain sustainable development. Long-chain levulinate esters (LEs) are a class of good biofuel candidates because they have similar structures to biodiesels and ...

Src Dependent Pancreatic Acinar Injury Can Be Initiated Independent of an Increase in Cytosolic Calcium [PDF]

, 2013
Several deleterious intra-acinar phenomena are simultaneously triggered on initiating acute pancreatitis. These culminate in acinar injury or inflammatory mediator generation in vitro and parenchymal damage in vivo. Supraphysiologic caerulein is one such

Calcitonin Gene-Related Peptide (Cgrp), Adrenomedullin (Am), Amylin, And Calcitonin (Ct) Receptors And Overlapping Biological Actions

The Scientific World Journal, 2001
CGRP, AM, amylin, and CT have in common N-terminal 6-7 amino acid ring structures linked by disulfide bridges and amidated C-termini required for biological activity.

Regulation of intracellular cyclic GMP concentration by light and calcium in electropermeabilized rod photoreceptors. [PDF]

, 1994
This study examines the regulation of cGMP by illumination and by calcium during signal transduction in vertebrate retinal photoreceptor cells. We employed an electropermeabilized rod outer segment (EP-ROS) preparation which permits perfusion of low ...

Calcium—Nutrient and Messenger

Frontiers in Plant Science, 2019
Calcium is an essential element needed for growth and development of plants under both non-stressed and stress conditions. It thereby fulfills a dual function, being not only an important factor for cell wall and membrane stability, but also serving as a

Calcium-rich Gap Transients: Solving the Calcium Conundrum in the Intracluster Medium [PDF]

, 2014
X-ray measurements suggest the abundance of Calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone.

Downregulation of TrkC Receptors Increases Dendritic Arborization of Purkinje Cells in the Developing Cerebellum of the Opossum, Monodelphis domestica

Frontiers in Neuroanatomy, 2020
In therian mammals, the cerebellum is one of the late developing structures in the brain. Specifically, the proliferation of cerebellar granule cells occurs after birth, and even in humans, the generation of these cells continues during the first year of

Got Calcium? [PDF]

, 2002
This lithograph answers the question: Where do the elements around us come from? Many are produced in stars, and liberated when these stars explode. It features an attractive image of the remains of an exploded star, taken by NASA's new Chandra X-ray ...
